Question: How to destroy a blocker?

Answer:

Battling a good blocker is tough, they generally can
keep the ball in play long enough for you to make a
mistake.

BLOCKING is precisely what I recommend you putting
back on them in return.

Telegraphing your playing style is DANGEROUS.If you have a
certain skill that is good, use it wisely (when the timing
is appropriate), not at a predetermined stage of the game.

I would suggest working the blocker with blocks, topspin and
loops of your own all over their side of the table; keep the
control in your court until the opponent gives you a high
return.

This is when you can utilize your loop kill shot or a smash to
put the point away.

I always recommend keeping the ball in play and letting
the opponent expose himself to defeat on his own.

Play your game like you might play a hand in poker,
reading your opponent's next move and taking advantage
of his bluff.
